2019-2021 Ram Cummins 6.7L Performance Parts & Delete Tuners

Your 2019-2021 Ram with the 6.7L Cummins diesel has serious potential—but you already know that. The stock setup comes loaded with emissions equipment (DPF, EGR, SCR systems) that cost you fuel economy, throttle response, and reliability. Our collection gives you the tools to take back control of your truck.

Tuning Options for 2019-2021 Ram 6.7L Cummins

We carry three proven tuner platforms: EFI Live, H&S Performance, Ez Lynk, and RaceMe Ultra. Each delivers real horsepower and torque gains, but they work differently. Some integrate with your factory dashboard. Others offer wireless tuning. Your choice depends on how much customization you want and whether you're deleting emissions equipment or running stock-legal tunes.

EFI Live Autocal V3 is the workhorse tuner for Cummins owners. It stacks with your factory gauges and handles everything from delete tunes to mild street performance.

H&S Performance Mini Maxx is rugged, intuitive, and built for guys who want solid power without complexity. It reads and clears codes, which matters when you're modifying engine systems.

Ez Lynk Auto Agent 3 lets you tune over your smartphone. Real convenient if you're chasing different tunes for different conditions.

RaceMe Ultra is the newer player—aggressive tuning for maximum deleted power.

Exhaust Mods & Delete Pipes

A DPF and CAT delete pipe clears out the restrictive aftertreatment hardware sitting under your truck. Paired with a delete tune, you're looking at real gains in spool-up speed and fuel mileage. EGR delete kits remove the exhaust gas recirculation circuit, which simplifies engine breathing and cuts carbon buildup.

What You Need to Know Before Buying

Your tuner choice matters. Some guys run stock tunes for reliability and warranty protection. Others go full-send with deleted emissions and aggressive power maps. Both are in this collection. Make sure your tuner supports 2019-2021 model year trucks—engine controller software changed between years, and compatibility matters.

We also stock the VIDEODASH+ premium dash cam for owners who want to document their truck's performance and capture what's happening on the road.

Will a delete tune hurt my engine reliability?

Not if you tune smart. Stock emissions equipment (DPF, EGR) actually creates more stress on your engine by trapping heat and carbon. A quality delete tune with proper fuel and boost management runs cleaner and cooler than stock. Avoid extreme tuning on marginal fuel or you'll see problems. Most guys who delete their 6.7L report better longevity because they're not fighting restrictive equipment.

Can I switch between delete and stock tunes on my tuner?

Yes—that's the whole point of aftermarket tuners like EFI Live and H&S Mini Maxx. You can load a delete tune for weekend driving and a stock-legal tune for situations where you need it. Switching takes seconds. Just understand that physically removing DPF/EGR hardware is permanent, so a stock tune won't put that equipment back in place.

What's the difference between EFI Live and H&S Performance for my 2019-2021 Cummins?

EFI Live offers deeper customization and more tuning files available from community developers. H&S is simpler and more plug-and-play. Both work great on 2019-2021 trucks. EFI Live edges ahead for guys building extreme power. H&S wins for straightforward reliability tuning. Pick whichever matches your goals.

Do I need a delete tune if I'm only doing an exhaust mod?

A tuner and a delete pipe work best together, but some guys run a delete pipe with a stock tune and see modest gains. You'll get way better results if you pair the exhaust mod with a tune that removes the DPF and EGR restrictions from the engine computer. That's when the real power and economy numbers show up.

Will deleting my 2019-2021 Ram Cummins throw a check engine light?

Not if your delete tune is dialed in correctly. Quality tunes from EFI Live, H&S, and Ez Lynk disable the emission fault codes. You won't throw lights. That said, cheap knockoff tunes or incomplete deletes sometimes leave sensor conflicts. Buy from established brands and make sure your tuner supports your specific model year (2019-2021 has different controller software than 2013-2018).

Can I tune my 2019-2021 Cummins with a tuner built for older years?

Not reliably. The 2019-2021 trucks use updated engine control software. You need a tuner specifically calibrated for your model year. Check the product description for year compatibility. Using the wrong tuner year can cause drivability issues or failure to load. We list exact year ranges for every tuner in this collection.

What happens to my warranty when I install a delete tune?

Dodge will likely deny warranty claims related to the engine, transmission, or emissions system. That's the trade-off. Most guys accept that risk because the reliability gain from removing emissions equipment outweighs factory warranty protection. Just understand what you're giving up before you order.
